Calderon is a quality pg who can pass and shoot the ball well... especially from beyond the arc and will play very well with Brandon.
Miller is an expiring contract and Rudy is a good player who needs more playing time.
While I'm dreaming. Maybe Toronto would also be willing to swap their 13th pick for the Blazers 22nd pick, along with the rights too Freeland, Claver and Koponen. Who knows.
